ReSharper nunit test show inconclusive when testing inheritance

Using Resharper Ultimate 10 and NUnit 3 Trying to write some unit tests that have a base class

[TestFixture]
public abstract class BaseTests
{
    protected BaseTests( /*some parameters */)
    {
        // some ctor code
    }

    [SetUp]
    public void Setup()
    {
        // some setup code
    }

    [Test]
    public void Test1()
    {
        // some tests code
    }

    [Test]
    public void Test2()
    {
        // some tests code
    }
}

[TestFixture]
public class TestA : BaseTests
{
    public TestA() : base(/* some parameters */) { }
}

[TestFixture]
public class TestB : BaseTests
{
    public TestB() : base(/* some parameters */) { }
}

My problem is that the unit test runner (resharper) shows those tests inconclusive even though if I debug none of the tests fail.

Ideas?
